I finally had enough of being mugged (and visitors being mugged) by our pack of Greyhounds every time the front door was opened. It was becoming more and more obnoxious as they fed off of each other's behaviour, so I decided to do something about it. The command "Perimeter" was born. Now it can be said from outside the door and you can hear them retreat to the carpeted area. They respect the word when guests arrive, retreat and wait for permission to greet. They hold "Perimeter" until the release of "okay" is given. Amazing.
Darby Crash is about the smartest in the bunch, and graciously demonstrates his understanding of the word "perimeter" when given the command in the entry hall of our house. This command has been just about the best thing they've all learned, second only to "Go Potty, NOW"
Guests in particular love to watch an entire pack of greyhounds retreat and hold their enthusiasm until they're released with the "okay" command. Sometimes we release them one at a time, which is an advanced skill the pack has learned. It's pretty awesome! Please note: normally I would not call Darby to come, and then immediately give him the perimeter command. It was done only for demonstration purposes to show how well he knows and respects the command. Also note that I'm not moving towards him when he backs up to the perimeter, he does this move on his own and keeps eye contact the entire time.
